Hi, I have exactly the same problem, I just take stadia with Grid, when I play the 3 initial events no problem at all, but I start a Fast run online, an then start the problem, first time with accelerate key, after that with directions keys. After some seconds or minutes the control come back......
Edit.... I start career... and it's totally frustrating.... I can't play one complete race without the problem..... I play with PC - Chrome Versión 80.0.3987.163 (Build oficial) (64 bits).
Edit, any moment, any direction or accelerate / brake Key.... in career mode, online mode, fast race.......
